8-1 Demand measurement
The following is an example of power management by monitoring the demand.
Ɣ Reducing the average power during a specific interval
Assume the interval to be 30mins.
In the figure below, the average power during Interval 1 is assumed to be
500kW and during Interval 2 is assumed to be 600kW.

Now, assume that the average power during the first 15 min. (the inspection
cycle) of Interval 2 is 600kW. The average power during Interval 2 can be
maintained at 500kW (same as Interval 1) by reducing the power of the last
15 min. to 400kW.

If say, the average power during the first 15 min. is 1000kW then the average
power during the second 15min should be 0kW to maintain an average power
of 500kW.
